                <p>This controls the power down of the SRAM banks in deep sleep mode. If this is set, then the power for that SRAM bank will be gated when the core goes into deep sleep. Upon wake, the data within the SRAMs will be erased. If this is not set, retention voltage will be applied to the SRAM bank when the core goes into deep sleep. Upon wake, the data within the SRAMs are retained. Do not set this if the SRAM bank is used as the target for DMA transfer while CPU in deep sleep.</p>

                <h3>Description:</h3>
                <p>This register enables the individual banks for the memories. When set, power will be enabled to the banks. This register works in conjunction with the MEMPWDINSLEEP register. When this register is set, then the MEMPWRINSLEEP register will determine whether power is enabled to the SRAMs in deep sleep. If this register is not set, then power will always be disabled to the memory bank.</p>

                <p>It provides the power status for all the memory banks including- caches, FLASH (0 and 1) and all the SRAM groups. The status here should reflect the enable provided by the MEMPWREN register. There may be a lag time between setting the bits in MEMPWREN register and MEMPWRSTATUS register, due to the need to cycle the power gate and isolation sequences to the memory banks.</p>

                <h3>Description:</h3>
                <p>This provides the power status for the peripheral devices- BLEL, PDM, PDM, MSPI2-0, SCARD, ADC, UART0 and 1, IOM5 to 0, IOSLAVE and MCUL (DMA and Fabrics) and MCUH (ARM core). The status here should reflect the enable provided by the DEVPWREN register. There may be a lag time between setting the bits in DEVPWREN register and DEVPWRSTATUS register, due to the need to cycle the power gate, isolation and reset sequences to the device power domains.</p>
